A process for upgrading oil feedstock which contain more than 50 % virgin oils, wherein the feedstock is hydrocracked to adjust the hydrogen content, flashed and/or hydrocracked to adjust the hydrogen content. Employing a vertical reactor shell (10) encloses and supports a stacked series of fixed porous solid beds of solid hydrotreating catalyst, as depicted by (12a) through (12e). A chargestock (6) is combined with a hydrogen rich gas (8) and introduced to the reactor (10) after undergoing appropriate heating means (9).

L'invention concerne un procédé d'amélioration d'une charge d'alimentation en huile contenant plus de 50 % d'huiles de première distillation, la charge étant soumise à un hydrocraquage de modulation de la teneur en hydrogène, c'est-à-dire soumis aux procédés flash et/ou à l'hydrocraquage. On utilise une cuve de réacteur vertical (10) qui renferme et soutient une série de lits durs fixes et poreux empilés de catalyseurs solides d'hydrotraitement, comme indiqué sur le schéma, de (12a) à (12e). Une combinaison de charge d'alimentation (6) et de gaz (8) riche en hydrogène est introduite dans le réacteur (10) après avoir été exposée à un chauffage approprié (9).
